"Cyclical Informality and Unemployment"

Abstract

The proportion of informal or unprotected workers in developing countries is large. In developing economies, the fraction of informal workers can be as high as 70% of total employment. For economies with significant informal sectors, business cycle fluctuations and labor market policy interventions can have important effects on the unemployment rate, and also produce large reallocations of workers between "regulated" and "unregulated" jobs. In this paper, we report the main cyclical patterns of one such labor market: Brazil. We then use the empirical regularities found in the data to build, calibrate, and simulate a two-sector search and matching labor market model, in which firms have the choice of hiring workers formally or informally. We find that our model, built in the spirit of traditional search and matching models, can explain well most of the cyclical properties found in the data. We also show that government policies that decrease the cost of formal jobs, or increase the cost of informality, raise the share of formal employment while reducing unemployment.
